Whoop replaces its new MG wearable due to bugs

Whoop is issuing replacements for its new Whoop MG wearable due to a critical bug rendering the device unusable. Users are reporting the fitness tracker becomes unresponsive shortly after setup. The issue causes the Whoop MG to disconnect from smartphones, even when charged, preventing data syncing. Affected users are reporting the device stops working within hours of use. Whoop is directing users to contact support and providing replacements. This problem comes shortly after Whoop's launch of the MG and 5.0 models, and follows a reversal of a decision to deny free hardware upgrades. The MG requires a $359 annual subscription.
